Fall is coming to an end, the sun sinks lower every day, and the chill of early winter has fallen across much of the northern hemisphere.
That means that, in places where leaves actually change color (AKA “not in Austin, where I live”), green has long given way to fiery reds and oranges, and that fire has since fallen to the ground, extinguished by garden rakes or decomposition, or blown out by brisk winds.
Hold on to these macro photos of color-changing leaves as a memory of the passing season. As the days have grown shorter, these plants have stopped producing as much green chlorophyll, and their carotenoids and anthocyanins shine through in bright canary and deep vermillion hues. You can also observe their veins, weaving beneath the leaf’s scaly epidermis, cutting cracks like a drying desert pond.
Here’s a less poetic diagram:
This is the beauty that lies in knowing, the science in the details, the wonder of the changing seasons.
